Practice: Classification using Dichotomous Keys Uh oh! Little Sammy's babysitter forgot to check for monsters under his bed when she tucked him in, and he found all of these when she left. Can you help him determine their names so he can ask them all to leave? Use the dichotomous key on the next page to help you.​

Answer 1

A dichotoums key uses morphological and molecular traits to classify organisms into different taxonomic groups.  

What is a dichotomous key?

A dichotomous key might be considered a useful tool to classify organisms. The key provides an easy and fast way for identification by describing different morphological and molecular traits, leading you to the correct taxonomic classification.

It is simple to read a dichotomous key. The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism. The key describes specific morphological oir molecular traits of organisms and you need to choose between the options which ones matches the ones of your organism.

Probably you might need an atlas or a dictionary to understand some of the technical terminologies. You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.

Since I do not have your dichotomous key, we are going to analyze a simple example using a group of 5 organisms. We will make the classification according to the description (organisms in the attached files).

Dichotomous key

Statement 1a ----------- The organism is a vertebrate ----------- Frog

Statement 1b------------ The organism is invertebrate ----------- Go to 2

Statement 2a ---------- The organism has a multisegmented

                                   and elongated body, with too many  ----- centipede

                                   legs.

Statement 2b ---------- The organism has a relatively short body

                                   and with fewer legs ------------------------------ Go to 3

Statement 3a ----------- The organism has 8 legs ----------------------- Spider

Statement 3b ----------- The organism has 6 legs ----------------------- Ant

As you can see, this a very simple example, but ilustrates how the key provides enough information for you to reah the correct option.

So in your example, your dichotomous key will probably provide you information about different traits such as body-color, number of extremities, hair, and other, and you will have to observe the all your individuals and choose which trait matches each of them.

Using your model, which of these would lead to an increase in carbon dioxide in the atmosphere? Select the TWO (2) that apply

Answers

Answer:

Carbon Dioxide is a gas it is always part of the atmosphere. However Carbon Dioxide gas can be removed and returned to the atmosphere.

Explanation:

Plants use Carbon Dioxide as one of the two main reactants in the process of photosynthesis. Photosynthesis removes Carbon Dioxide from the atmosphere turning the Carbon into Carbohydrates, such as cellulose found in wood.

Cellular Respiration, burning coal, wood, gasoline, turn the Carbon-based molecules back into Carbon Dioxide and water. These Oxidation reactions return the Carbon Dioxide to the atmosphere

Cross a female with normal color vision, but whose father was colorblind, with a man who has colorblindness. Tell the expected phenotypic ratio of the offspring

Answers

2/4 chance of the child will be colorblind

If a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is  50%.

What is Colorblindness?

Colour blindness is linked to the X-chromosome defect. It is a condition in which a person is unable to see the colors or differences in colours or its abilities decreased.  For example,  he was unable to distinguish between the colour of traffic lights, colour of fruits or choosing clothes.

Colour blindness is to be present on all X chromosome within the individual have to be affected; so the man has only one X-chromosome and women have two, the chances of colour blindness is much more higher in men as compared to women.

In the above example due to genetic inheritance of the mother from her father, the chances of colour blindness in their child is 50% because each parent is a carrier having X chromosome.

In this case chances of inheriting colour blind X chromosome would be double as likely for female child because both mother and father are the carriers of X chromosome of colour blindness.

Thus, if a female with normal colour vision, but her father was colour blind crosses with the man who has colourblindness, the phenotypic ratio of the offspring is  50%.

After each bar press, a laboratory rat receives electric stimulation to its brain. The rate of bar pressing increases. This is an example of operant conditioning given by Skinner.

What do you mean by electric stimulation?

Electric stimulation may be defined as the process that uses the device to transmit gentle electrical pulses via the skin.

Operant conditioning is associated with the hit and trial conditioning method which was proposed by B.F Skinner. This experiment falls in association with the behavior and stimuli of an organism or model.

Therefore, after each bar press, a laboratory rat receives electric stimulation to its brain. The rate of bar pressing increases. This is an example of operant conditioning.
